See if the steering shaft was lengthened for the lift:

Also might be the plate where the shaft passes through the firewall that needs to be re-centered. The u-joints can be popped apart and regreased if needed. Mine were getting a little notchy and after cleaning and greaseing, they operate much smoother.
